Definitions
- radioactive materials are detected by autoradiography, a process wherein the substrate is placed in superposition over a piece of X-ray film and the radiation "exposes" the silver halide. Sometimes this is enhanced by using a phosphor screen behind the film. Sometimes it is done at low temperature to increase sensitivity.
- a common need is a means of marking the substrate in order for the researcher to be able to clearly identify his system and, very importantly, to facilitate proper match up of the areas on the substrate with their corresponding exposed areas on the film.
- radioactive marker usually take the form of a colored ink to which is added appropriate amounts of outdated radiolabeled materials.
- Application is often by adaptation of commercial pens or simple dotting devices.
- the intensity of marking actually attained on the film is dependent not only upon time of exposure and radionuclide energy, but also is affected by the plastic overlays commonly used and, in some special cases, temperature.
- the present invention relates to a process for the labeling of materials to be autoradiographed using a phosphorescent material, such as an ink effectively avoiding all of the radioactivity associated disadvantages cited above. In the Examples below, this is achieved by the use of a carefully selected phosphor with decay time adequate to allow convenient and effective application.
- U.S. Pat. No. 2,396,219 discloses a phosphorescent marking crayon using a zinc-cadmium activated by copper phosphor.
- U.S. Pat. No. 3,631,243 discloses a device for marking indicia on photographic film in a housing involving insertion into and withdrawal from the housing a unit bearing the indicia and a phosphorescent source of light to expose the film.
- the present invention relates to a process of marking autoradiograms with the emissions from a phosphorescent material, preferably an ink, which contains a doped zinc sulfide phosphor, and optionally a visible pigment, a vehicle and a binder.
- the ink is marked onto the surface of a substrate to form indicia which then are used to provide activating radiation to form a latent photographic image in the photosensitive layer of an X-ray film which is developed along with the latent photographic image formed by exposure to the substrate.
- the ink used in the present invention is based on phosphors which are of the hexagonal Wurtzite (C6mC) form of zinc sulfide doped with various trace metals.
- Suitable metal dopants include, but are not limited to silver, boron, barium, calcium, cadmium, copper, magnesium and silicon. Generally several but not all of the above metal dopants are present in the zinc sulfide phosphor. Generally the amount of individual metal dopants present will vary from 5-1000 ppm.
- the radiation emission (light decay) must be long enough to allow appropriate manipulations to be performed in the darkroom prior to film placement. Secondly, and most important, there must be adequate emission of light at the appropriate wavelength to expose the film.
- the major high speed autoradiography film in use today is primarily sensitive to blue light (e.g., Kodak XAR-5).
- blue light e.g., Kodak XAR-5
- some green emitting phosphors peak radiation wavelength from 507-517
- the preferred green emitting phosphors are ones based on hexagonal Wurtzite zinc sulfide doped with 200-1000 ppm barium, 200-1000 ppm calcium, 50-250 ppm copper, 50-250 ppm magnesium and 20-100 ppm silicon; and another one based on hexagonal Wurtzite zinc sulfide doped with 5-25 ppm silver, 100-500 ppm cadmium, 50-250 ppm copper, 50-250 ppm magnesium and 50-250 ppm silicon.
- the phosphor will have a particle size distribution peak between 10 and 15 microns.
- the particular ink formulation is not particularly critical and both water-immiscible organic solvent based inks and aqueous acrylic inks have been used satisfactorily. Generally the ink should contain from 5-20 weight percent of the phosphor.
- the materials subjected to autoradiography for use in the present invention are sheet-like members containing a distribution of radioactive material in a gel supported on a film of material such as nitrocellulose, microporous nylon (charged or uncharged) diazotized benzyloxymethyl cellulose (DBM), diazotized phenyl thioether cellulose, diethylaminoethyl cellulose, polyvinylidene fluoride or a tissue section appropriately fixed and mounted, etc.
- the matrix to be detected is impregnated with a fluor to convert the radiation emissions to light.
- the entire matrix bearing the phosphorescent ink is exposed to actinic light to charge up the phosphor contained therein.
- actinic light Ordinary light as found in a typical laboratory is satisfactory for this excitation and little is to be gained by using high intensity illumination of the substrate bearing the phosphorescent indicia. In fact, fairly low intensity light can be used and generally a very brief exposure (less than a minute) to actinic radiation is adequate to activate the phosphor.
- the long decay phosphor allows considerable time to ensue before the radiolabeled matrix must be superimposed on the X-ray film.
- the device used to apply the phosphor containing ink to the substrate preferably is a capillary pen or a ball-point pen although other means such as typewriter ribbons, hard graphite compositions, etc. can be used.
- the indicia marked on the autoradiogram serves several purposes including identification matching to the original substrate, orientation and registration.
- a phosphorescent ink is prepared by blending 98 volume percent of a white ink containing 9.81 weight percent titanium dioxide pigment, 28.84 weight percent aluminum silicate clay, 19.22 weight percent chlorohydrocarbons consisting principally of 1,1,1-trichloroethane, 23.07 weight percent aromatic hydrocarbons, 3.2 weight percent wax resin, 14.42 weight percent mixed resins and 0.8 weight percent fumed silica, a volatility of 50% and a specific gravity of 1.4 with 2 volume percent of a green ink containing 10.9 weight percent lead chromate, 1.6 weight percent polychlorinated copper phthalocyanine, 4.1 weight percent wax resin, 16.22 weight percent mixed resins 28.9 weight percent aluminum silicate clay, 17.0 weight percent chlorohydrocarbons consisting principally of 1,1,1-trichloroethane, 20.6 weight percent aromatic hydrocarbons, a volatility of 50% and a specific gravity of 1.4.
- the green ink prepared above is blended with the following phosphor in a ratio of 10 g phosphor per 100 g ink.
- the phosphor is a hexagonal Wurtzite (C6mC) form of zinc sulfide doped with about 450 ppm barium, about 450 ppm calcium, about 100 ppm copper, about 100 ppm magnesium and about 50 ppm silicon.
- a capillary type marking pen is filled with the resulting phosphorescent ink.
- a dried gel prepared from an electrophoretogram of radioactive proteins is marked on its gel surface with the pen both to identify the radiogram and to provide a plurality of location markers.
- the gel in the light, is wrapped with a polyvinylidene chloride film and under a safe-light mounted in an X-ray film cassette using Kodak XAR-5 film where the X-ray film is exposed to the gel for 60 minutes.
- the X-ray film is then developed in the conventional manner. After development the marks made on the gel with the pen are clearly visible as dark lines on the X-ray film.
- Example 1 is repeated except the phosphor used is a hexagonal Wurtzite (C6mC) form of zinc sulfide doped with about 10 ppm silver, 250 ppm cadmium, about 100 ppm copper, about 100 ppm magnesium and about 100 ppm silicon.
